Cartographic information transmission and display method, cartographic information transmission and display system, terminal and server

Abstract

The embodiment of the invention discloses a cartographic information transmission and display method, a cartographic information transmission and display system, a terminal and a server. The method comprises the following steps of: sending a cartographic information acquisition request to the server by the mobile terminal, wherein the request comprises a cartographic feature required for acquisition, and the cartographic feature consists of cartographic information within a geographic area; receiving the cartographic information acquisition request by the server, separating cartographic information corresponding to the cartographic feature in the request from complete cartographic information stored per se and sending the separated cartographic information to the mobile terminal; and receiving the cartographic information by the mobile terminal, drawing a cartographic picture according to the cartographic information and displaying the cartographic picture. The cartographic information transmission and display method, the cartographic information transmission and display system as well as the corresponding mobile terminal and the server can be used for providing more specific and nichetargeting cartographic information service for mibile terminal users, and the data transmission quantity between the mobile terminal and the server can be reduced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for transmitting and displaying map information, a system for transmitting and displaying map information, and a corresponding mobile terminal and server. Background technique [0002] With the advancement of electronic technology and mobile communication technology, the functions of mobile terminals are continuously enhanced, and more and more applications can be realized. Applications related to map information such as electronic maps and electronic navigation are becoming more and more popular. [0003] Judging from the current situation, there are mainly three ways for mobile terminals to realize map information query such as electronic maps and electronic navigation: one is that the mobile terminal itself stores a copy of map information, and calls the corresponding part for display according to the user's query requirements; It is online navigation.

Problems solved by technology

[0005] The defect of the first implementation method is that the electronic map stored in the mobile terminal itself is often not detailed enough due to the limitation of volume and cost, and in today’s fast-growing urban construction, the electronic map stored in the mobile terminal itself will soon be lost. Accuracy; the defect of the latter two implementation methods is that the server sends all the map information corresponding to the geographical area that the mobile terminal requests to obtain map information, the data traffic is large, the information interaction time is long, and it cannot meet the needs of the mobile terminal in a targeted manner. The user's specific query requirements

At the same time, due to the influence of the display area of ​​the mobile terminal, the map information issued by the server cannot be very detailed. Therefore, it is more difficult to provide more specific and targeted map information services for mobile terminal users.
